The Rosemount Analytical TCL Total Chlorine Analyzer is intended for the determination of total chlorine in water,
including the determination of chlorine in seawater. The Rosemount Analytical TCL system consists of a sample
conditioning unit, a sensor and either the 1056 Dual Input Analyzer (1056-24)
or 56 Dual Input Analyzer (56-24). With no metal wetted parts this Rosemount
Analytical TCL system is ideal for seawater. The sample flow rate is approximately a low 15mL/minute resulting in very
little waste. The reagent-based system measures true total chlorine.

The Rosemount Analytical TCL Total Chlorine Analyzer is a sample conditioning system that permits a single sensor to
measure total chlorine in water. The sample conditioning system continuously injects a solution of acetic acid (vinegar)
and potassium iodide into the sample. The acid lowers the pH to between 3.5 and 4.5 and allows total chlorine in the
sample to quantitatively react with the potassium iodide concentration, and the analyzer displays the total oxidant
concentration in ppm as Cl 2.
